Meet the Pink Star diamond, a whopping 59.60-carat Flawless Fancy Vivid Pink diamond that just sold in Hong Kong for $71.2 million, breaking records for the most expensive diamond or gemstone ever sold at auction. But that's not the only record this gem holds — it's also the largest internally Flawless, Fancy Vivid Pink diamond the GIA has ever graded.

Originally a 132.5 carat rough diamond, the Pink Star took two years to cut and polish after being mined in Botswana by De Beers in 1999. In 2013, it made an appearance on the auction scene when it sold for $83 million to diamond cutter Isaac Wolf, but the transaction fell through when he couldn't come up with the money, leaving Sotheby's with the stone.

Renowned jeweler Chow Fai Fook is the proud new owner of this oval mixed-cut beauty, originally mined by De Beers in Africa in 1999. The previous record holder for most expensive jewel was the 14.6 carat Oppenheimer Blue, which sold for $58 million at Christie's last May.
